Is a thermal insulation coating needed on the outside of the regenerator?
Thread Content
The outside of the regenerator is coated with heat-changing paint, as well as an insulating coating. How much thermal energy can a thermal insulation coating recover? Everyone is welcome to actively discuss how each device is constructed.
The interior of a regenerator is generally lined with heat-insulating and wear-resistant materials, while the outer wall usually does not require any insulation.
In the chemical plants I’ve seen, the exterior is coated with a color-changing coating that changes color when overheated, and insulation is required on the outside

I have also never seen any system for dissipating this heat, nor is such a thing mentioned in the design specifications; I have only seen it used for roasting sweet potatoes. :Lol, the reactors themselves are irregular in shape; there are numerous openings for processes, instruments, and utility systems on their walls. The pipes, valves, and measuring instruments connected to them are very complex. In addition, there are various special-shaped devices such as regeneration units, standby units, circulation inclined tubes, external heat exchangers, and slide valves. In most cases, the flanges are located quite close to the reactor walls, and increasing the insulation thickness makes it impossible to carry out effective inspections, tests, or repairs ； More importantly, once insulation is in place, it becomes impossible to detect the hot spots in these two devices in a timely manner to take corrective action; by the time severe leakage of the catalyst at temperatures above 700 degrees occurs, the consequences will be catastrophic.
No insulation is used on the outside; a high-temperature resistant anti-rust paint is applied.
The interior of the regenerator is usually lined with heat-insulating and wear-resistant materials, while the outer wall does not require insulation； An overheat-color-changing coating can be applied on the outside, allowing for observation when the temperature exceeds a certain level
No insulation? Won’t it result in heat loss? Aren’t you afraid of water in rainy weather?
